Abstract
Raising the drinking age twice in New York State in the 1980s might have created a generation of "serial beginning drinkers". Findings indicate that when young adults become beginning drivers, their chances of drinking-driving increase; when they become serial beginning drivers, their involvement in drinking-driving remains high over time. The beginning drinkers belong to a special historical period and are only composed of birth cohorts of 3 or 4 years (mainly early 1960s). The effect of the serial beginning drinker should fade out as those birth cohorts grow into maturity.
